The load rating of the tire displays the weight a tire can carry. The product of the load capacity of a single tire and the number of tires determines the load carrying capacity of all the tires combined. The rating of 121 shows that it has a load capacity of 3297LBS.

What is a 120 load range?

Light Truck Tire Load Index

For example, a light truck tire with a load index of 120/116 means a load capacity for a single tire of 3,086 pounds and a load capacity of 2,756 pounds for two tires.

What is a load rating chart?

Using the Tire Load Index Chart

In other words, it's the amount of weight your tire can support safely. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure. Multiply that by four tires (4 x 1,389 = 5,556 pounds) to get your car's maximum load carrying capacity.

What load range is a 14 ply tire?

Load Range Capacity and Ply Ratings

This article focuses on 14 ply trailer tires (load range G), which is the highest capacity you can get. 14-ply rated trailer tires can sustain pressures of up to 110 psi (760 kPa), and weight of over 4,000 lbs per tire.

What load rating do I need?

To roughly determine the load range capacity for each individual tire, take the vehicle's gross weight and divide by four. If the vehicle gross weight is 4,500 pounds, each tire should be able to safely support at least 1,125 pounds.

Speed Rating & Load Index

Is a higher load rating better?

The load rating can be located on the sidewall of all tyres and is represented by a numerical value. The higher the load rating number, the stronger the tyre. Tyres with a higher load rating can take a greater amount of air pressure, which means they can also carry heavier loads.

What is a 113 load index?

This two-digit or three-digit code represents your tire's load index. The higher this number, the higher the weight each tire is rated to carry. For example: A tire with a size of “275/55R20/113T” has a load index of 113. A tire with a size of “225/65R17/102H” has a load index of 102.

Are all Load Range E tires 10 ply?

To summarize: ply ratings and load ratings are systems of measurement for load carrying capacity. Load Range E tires are equivalent to a 10-ply tire.

Are all LT tires 10 ply?

LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall. The performance trade-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.

What load range is a 6 ply tire?

For example, a C Load Range specifies that a tire is equivalent to a 6-ply construction tire.

What does 12 ply mean on tires?

The 12-ply rating doesn't actually mean that the tire has 12 different plies or 12 layers. It's really just the way to classify the tire and to ensure that the manufacturer tested it to meet that 12-ply rating and/or that Load Range F requirement.

What load range tire do I need for towing?

To be completely safe when towing with your truck, you will need 10 Ply or Load Range E tires. The best 10 Ply tires for towing should be capable of at least 3,000 lbs of weight per tire and do it while giving you safe driving experience with a high amount of grip and traction.

What does XL mean on a tire?

XL (or Reinforced) tyres are 'extra load' tyres – they indicate that a tyre is reinforced to be able to withstand a higher load than other tyres of the same size.

Can I buy a tire with a higher load rating?

If you're thinking about up-sizing, you can switch to a tire with a higher load index, because that means your tire can safely carry more weight, but you can never go down.

What is a standard load tire?

Standard Load (SL) Tires

Standard load tires are manufactured mostly for regular passenger vehicles that are used for average, everyday driving and don't need to carry or withstand heavy loads. Since they're the most common passenger tires, they'll either be marked with SL on the sidewall or nothing at all.

Do load range F tires ride rough?

Typically, an F rated tire will ride a bit worse than an E rated tire, but there are some exceptions. Load range refers generally to a side ply rating, while load index refers to a tire's weight rating.

What's the best speed rating for tires?

As manufacturers developed bigger and better tires, it became necessary to regulate performance at standardized speeds to ensure safety. The "Limited V" category of 250 km/h (149 mph) was then created, and eventually the "Z" speed rating was added as the top speed rating.

Is a higher ply tire better?

The more ply, the more sidewall strength. When your sidewall isn't strong enough, the load squashes the tires down into the road. The tread then pushes into the ground and spreads out in a way that was never intended by the manufacturer, leading to a blowout.

Are 12 ply tires good for towing?

Load Range F can also be classified as 12 Ply tire. These Load Range F tires have a maximum load index of 95 PSI and are the perfect choice of tire for towing very large trailers and trucks.

Is 10 ply or 14 ply better?

So when inflating trailer tires be sure to go to the max psi. With that said the 14 ply tires will definitely hold up better than the 10 ply.
